KOEO code 14
I'm getting a code 14 which, according to my actron scanner book, means "the ECA has detected an intermittent loss of PIP signal during recent operation". The Haynes manual says this refers to an engine rpm sensor circuit fault. I've already replaced the ignition module along with various other parts, still it runs rough. Also, I replaced the TPS and now I have to keep slight pressure on the throttle to keep it running. Could it be that I've purchased a bad IM and/or installed the TPS improperly? By the way, it's an '89 3.0L.
Thanks for any help,
Chuck

[updated:LAST EDITED ON 17-Jan-02 AT 02:31 PM (EST)]14 is usually an impending failure of the Profile Ignition Pickup (PIP) sensor. I don't have the 3.0 engine, but I believe the sensor is located in/on the distributor. (Some of the other regular contributors have the 3.0 and may be able to provide additional insight.) The PIP sends a signal to the ECU which is then used for various functions: it provides a crankshaft position reference for fuel injection, correct and variable spark timing, and proper fuel pump operation. I would check the PIP sensor first for a loose wire connection, a bad ground to distributor or a dirty pickup. Then look at replacement if none of the above solve the problem.

appreciate the info.I'll give your suggestions a try. Another $30 for another IM is acceptable if it will fix the problem. As I mentioned in my earlier post, I'm having some trouble getting it to idle on it's own. Is there a particular method of installing the TPS?

Sorry, I didn't notice you had already replaced the ignition module. If you are still having problems, it may be possible your mass airflow sensor (MAF) is dirty. Carefully remove the sensor and clean it with electronics spray and see if this solves the problem. The TPS is usually a straightforward replacement, not requiring any sort of calibration. Also, be aware that after a 15 minute power loss, the ECU loses its memory. It takes a day or two for the ECU to "relearn" the operating profile for the engine. It re-sets to default mode on start up and may be why you are now having problems with the idle, although I think the MAF is the culprit.

Thanks for the advice.I cleaned the ignition module and the MAF (also replaced)Seems to be running well, erased codes and retested, now I'm getting all 11s 
. Probably the "relearning" process you mentioned since it was without power for quite some time.
I appreciate all the helpful advice,
Chuck

I happened to be looking over the AllData CD for my '89 today, and ran across a TSB on the Code 14 thing.
I can't cut-n-paste this one, but I'll type in the highlights:
Code 14 diagnostics, manual correction.
{models listed that this covers}
Issue: The continuous memory code 14 of test step N1 shown on pages yadda yadda has been revised.
{junk and errata}
Code 14 indicates two successive erratic profile ignition pickup (PIP) pulses occurred, resulting in a possible engine miss or stall.
Possible causes:
* Loose wires/connectors.
* Arcing secondary ignition components (coil, cap, rotor, wires, plugs, etc.)
* On-board transmitter (2-way radio)
{If the problem is not one of the above}
{testing described to check for other codes 18, 28, 48, and what their causes are; basically harness checks for bad connectors}
Regards,
Al S.
